<h1>Understanding how data is displayed: Incremental Fetch</h1>
<p>Incremental fetch determines how and when your data displays. The less 
 amount of data that the software has to return, the faster you will get 
 your report results. Two instances when MicroStrategy uses incremental 
 fetch are when you run a report in Outline Mode or when you are adding 
 attribute elements to a filter. </p>
<h2>How incremental fetch is used in a filter</h2>
<p>When you run a report and want to add an attribute element filter to 
 it, incremental fetch determines how many attribute elements will display 
 in the <span style="font-weight: bold;"><B>Available</B></span> field at one 
 time, as shown in the image below. This helps limit the amount of data 
 that MicroStrategy has to return at one time, which allows you to get 
 your information faster. </p>
<p>&nbsp;</p>

<h2>How incremental fetch is used in Outline Mode</h2>
<p>When you run a report in Outline Mode, incremental fetch determines 
 how much data to return based on which level you are viewing. See the 
 image below for the following example. When you view a report in Outline 
 Mode, you can click the numbered buttons at the top of the report to view 
 data at specific levels. For instance, if you select level 2, then incremental 
 fetch will display the data available on level 2, which is all of the 
 columns and rows, or everything on the report. If you were to select level 
 1, then only the Customer Region column and any available metric totals 
 would display. </p>
<p>Using Outline Mode is useful when you want to display only a subset 
 of the data on a report. If you only want to see the total revenue for 
 the Northeast customer region, then it makes sense to view the report 
 in Outline Mode. </p>
